Product Specification:
ODEX system Eccentric Casing system is suitable for drilling water wells, geothermal wells, short mircopiles,medium mini-type grouting hole of building,damand harbour project.
- Rapid removal of cuttings; High penetration rate, especially in resistant rock formation;
- Easy soil and groundwater sampling during drilling;
- Possible to measure yield estimate at selected depth in the formation;
- Advantageous in unconsolidated formations with a high risk of caving
Casing drilling involves drilling and casing a well simultaneously through unstable ground conditions, In casing drilling process, down the hole tools can be retrieved, through the casing on wire-line, meaning tool recovery or replacement of tools
can take minutes versus hours under conventional methods. This process employs wire line-retrievable tools and a drill-lock assembly, permitting bit and BHA changes, coring, electrical logging and even directional or horizontal drilling. Once the casing point is reached, the casing is
cemented in place without tripping pipe.
Casing drilling has been employed in many countries as an effective method of reducing the overall drilling costs by reducing drilling time and drill string problems
encountered during conventional drilling process.
